- A plic tion-retina 15, .1944," Serial No. 522,464"

v seams. ,(c1. los -'1') This-invention relates toicomposition shingles} and' has for the primary object-the'provision of shingles of the above statedcharacterwhichwill have a much longer life,- less apt to leak an'd'will' be positively prevented from curling-'or"being lifted out of position by Wind."

Another object of this invention is the provision of-a shingle of doublewall construction; one wall oithe inner wall forming a leakproof back ing to the other or outer wall, sothat's'hould the outer wall crack or become damaged. water still will be positively excluded; v f

A'further object of the invention isthe provision of a'concealing and protecting foldf'in the outer wall to receive-a nailing strip atthe butt edge of the 'adjacentor overlapping shinglewhich whennailedin position, will havethe nails hid den fromvi'ew and protected againstrweather elements and each shingle will be- 'firml'y an ch'ored'at the butt edge torprevent the shingle I from raising up either b'y'w'ind or by deteriora tion'of the material of theshingle from weather elements.

'A further Object of" the invention-is 'theprovi sion of ioverlaps of the shingle strips-at the ends thereofwhich with theinterlocking of theshim gle strips at the longitudinal edges thereofbring about a complete sealbetween theshingle strips with each shingle--stripfirmlyfixed in place."

With these and other objectsin'view as'will'become more apparentasthe description proceeds, the invention consists in certain novelfeatures of construction, combination andarrangementof parts as Will'be hereinafter more fully-described and claimed; h Y

For a complete understanding of my in ven tion, reference is to'be had to the following-(lei seription and accompanying drawings, inwhich Figure 1'. is a-planvie'w il-lustrating a plurality of shingle strips constructed in accordance with my invention and'showing' the shingle'strips in a'laid and secured position. 1

'form' of my invention.

Figure 7 is-a plan view illustrating a modified "the Figure Ms 2. detail sectional view taken'o line 8-8 of Figure 7. Figure 9'is a plan view illustrating another modified form of my invention;

Referring in detail to the drawings; the numeral 5 indicates a blank from which the shingle or-shingle strip is made. 'Ihematerial'used in the construction of this blank may be of anyof'the well known kinds now employed in themaking of composition shingles. Theblank 5 is'folded onthe lines A,B, C and D.- It'will benoted from Figure Gthat the lines extend longitudinally of the-blank 5; Theblank is-first'folded on'itself'at the line A forming walls 6 and 1. When the shingle strip is completed'from theblankthe wall 1 isdisposedoutermost and will be hereinafter referred to asthe outer wall-and 6 the inner wall of the shingle strip; When the blank is'folded on theline Alto form the Walls 6 andl, the'wall 7 will be of the greatest width and 'is folded on the lines B,*'C to form a channel's extending the full length of the completed shingle strip; The wall 'ljis' also folded on the line D toform a nailing or attaching strip 9' of a length equal to the length'of the channel '8. At spaced intervals the wallj'l isprovided with/slots In extending from a,

point adjacent the fold line'C to the fold line D.

In' the manufacture of the blank it may be preferable'to have the walls 6 and 1 taper in thickness from the free edge of the wall 6 tothe fold' line A'and from the free edge'of the wall 1 to either thefoldline C'or B. The end edges of the blankare' stepped; as shown in Figure 6, so that one end of the wall 6" will protrude beyond a corresponding end of the wall 1 to form an extension |l=while the other end'of the wall 6 will be spaced-inwardly from the corresponding end edge of the'wall I so that when-theshingle strips are assembled on a decking l2 the extension ll of one shingle stripwill be'received within the cutout end of the adjacent'shinglestrip.

In folding the na'iling or attaching strip'on the wall 1 it is 'bentfin-the direction" of the Wall Band receives the'free longitudinal edge thereof as shown in Figuresi and 5.

In assembling the shingle strips on the decking I2, nails or like fasteners is are driven through the attaching strip into the decking] While theshingle strip is being secured in posiously laid shingle strip. The nail or fastener is driven through both walls 6 and I and attaching strip, as clearly shown in Figure 3. The shingle strip which is being secured in position is then swung to overlie the nails or like fasteners with the wall I disposed outermost, the slots I!) thereof giving the appearance of individual shingles of substantially rectangular shape. It will be seen that the slots 10 are underlaid by the wall and open outwardly through the lower or butt edge of the shingle for drain purposes.

The attaching strip being arranged in the channel 8 of the adjacent shingle strip and secured by the fasteners I3, brings about securing of the shingle strips at the butt edges so as to prevent the shingle strips from curling upwardly or being blown up by wind. Also it will be seen that the inner wall 6" of each shingle strip underlies the outer wall and with the butt edge firmly anchored in place and the extension ll fitting under the end of the adjacent shingle strip, each shingle strip will be completely sealed at all edges and thereby exclude water, moisture or the like.

It is to be understood that the shingle strips may be of arm selected color and of any selected composition of materials. Further, it will be seen that each shingle strip being of double wall thickness will have a much longer life owing to the fact that the inner wall to a great extent is protected against weather elements and will form a backing and reinforcement for the outer wall so that should the outer wall crack or deteriorate from weather, rain or the like will be prevented from getting through by the inner wall 6.

Referring to my modified form of the invention as shown in Figures '7 and 8, the shingle strip l5 may be of either a single or double wall type. However, in the drawings the shingle strip I5 is shown of a single wall type and the blank thereof is cut to form the extensions 5 and nailing tabs H, the extensions 16 being provided with converging edges so that when the strips l5 are assembled they will give the appearance of shingles of hexagonal shape. Also when the strips are assembled in a manner like the assembling of the shingle strips shown in Figures 4 and 5, the attaching tabs are bent to underlie the shingle strip therebelow and are secured in position by nails or like fasteners driven therethrough and through the main body of the shingle strip therebelow, so that the shingle strip being attached when bent downwardly over the shingle strip thereunder will cover and conceal from view as well as protect the nails or like fasteners.

Referring to my modified form of the invention, as shown in Figure 9, the shingle strip I8 is constructed in a similar shape to the shingle strip l5 except that the spaces between the extensions I9 are cut deeper into the body of the shingle strip with parallel edges 20 to receive the attaching or nailing tabs H with opposite edges thereof abutting the edges 20 to prevent shifting of the shingle strips with relation to each other and to greatly assist in the mounting and securing of the shingle strips in place on the decking.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described the invention, what I claim is:

1, In a composition shingle, inner and outer elongated integrally connected walls, and an attaching strip integral with one of the longitudinal edges of the outer wall and underlying both of said walls, said front wall being folded uponv itself to form a channel open in the direction'of the lower longitudinal edge of the outer wall to receive therein an attaching strip of a correspondingly constructed shingle.

2. In a composition shingle, inner and outer elongated integrally connected walls, an attaching strip integral withone of the longitudinal edges of the outer wall and underlying both of said walls, said front wall being folded upon itself to form a channel open in the direction of the lower longitudinal edge of the outer wall to receive therein an attaching strip of a correspondingly constructed shingle, and fasteners driven through the inner and outer walls and the attaching strip.

3. In a composition shingle, a shingle strip including inner and outer integrally connected walls, an attaching strip integral with the lower longitudinal edge of the outer wall and underlying. both of said walls, said outer wall having a channel formed therein and opening outwardly in the direction of the lower longitudinal edge of the outer wall to receive an attaching strip of a correspondingly constructed shingle strip.

4.-In a composition shingle, a shingle strip including inner and outer integrally connected walls, an attaching strip integral with the lower longitudinal edge of the outer wall and underlying both of said walls, said outer wall having a channel formed therein and opening outwardly in the direction of the lower longitudinal edge of the outer wall to receive an attaching strip of a correspondingly constructed shingle strip, said shingle strip having opposite ends thereof cut away in stepped formation to form an extension at one end of the shingle strip and a space to receive a like extension on a correspondingly constructed shingle strip.

5. In a composition shingle, a shingle strip including inner and outer integrally connected walls, an attaching strip integral with the lower longitudinal edge of the outer wall and underlying both of said walls, said outer wall having a channel formed therein and opening outwardly in the direction of the lower longitudinal edge of the outer wall to receive an attaching strip of a correspondingly constructed shingle strip, said outer wall having relatively spaced slots extending from the attaching strip into said channel.
